Your body. Decoded.
PACE Band / Screenless health system
A titanium band that reads your heart, sleep and recovery around the clock, then turns the signal into clear daily direction.
01Screenless by design
No screen. No noise. Only signal.
PACE Band reads your heart up to 256 times a second, follows every stage of sleep and turns it all into one clear answer each morning: how ready you are to perform.

Every run
Pace and heart rate from each outdoor run refine the estimate. No lab test, no treadmill protocol.
Terrain aware
Climbs, heat and altitude are corrected for, so a hilly day does not read as lost fitness.
Race ready
Your estimate drives predicted finish times from 5K to the marathon, updated after every session.

05Materials
Engineered to disappear.
- 01
Grade 5 titanium core
Machined from a single billet and bead-blasted to a satin finish. 11 grams, 8.6 mm thin, with no seams to catch on a sleeve.
- 02
Double-weave strap
Recycled nylon over an elastane core. Breathable, quick-drying and soft enough to forget you're wearing it at night.
- 03
Domed sapphire window
A sapphire lens presses the optical array gently into the skin, keeping the signal clean through every stride and rep.
- 04
MagLock clasp
Two titanium halves meet with 40 newtons of magnetic hold. On and off with one hand, secure through a sprint finish.


06Three finishes

07Field tested
Worn by people who measure everything.
“I stopped looking at my wrist mid-race. The band tells me what I need when I need it, through a haptic nudge, and nothing else.”
Lena HartmannUltra-trail runner · Field team since beta · 2,140 km logged “My HRV trend flagged overreaching two days before I felt it. I backed off, and set a 2k best the following week.”
Marcus BellCompetitive rower · Field team since beta · 318 sessions “It disappears at night. The sleep and recovery data has become the most honest coach I have.”

08Questions
Good to know.
Because the most useful data is the data you don't stare at. Without a display, the band is thinner, lighter, lasts up to 10 days and never pulls your attention mid-session. Live numbers stream to your phone when you want them, and silent haptic cues tell you when you drift out of your target zone.
No. Every metric, every insight, your complete history and full data export are included with the band. Software updates that add new features are free for the life of the product.
Double-tap the core and a short haptic pulse confirms the session has started. Runs, rides, swims, walks and strength sessions are also detected automatically, and you can start any of 90 activity types from the app.
In validation against chest-strap ECG, PACE Band measured heart rate within 1.8 bpm on average across 40 activity types and tracked overnight HRV with a 0.97 correlation. Accuracy can vary with fit, so wear the core snug, one finger above the wrist bone.
Yes. The band is rated 10 ATM and tracks pool and open-water swims, including distance, stroke rate and SWOLF. The woven strap dries in about 20 minutes.
